Showing "unused" questions

With a growing list of questions, it would be helpful, to see which questions are already used in a session and which are “unused”…

Maybe next to each question, it could be shown, in which sessions these are used. It would be helpful to sort the questions also according the usage.

Dear @HPEclic,

I have added a feature request on your behalf: Questions - Show where questions have been used | KlickerUZH.

This should be something that can be done fairly quickly as part of the new question pool design.

Best,
Roland
